Alterations of activity of cholinergic neurons in vivo are followed by parallel changes in Na-dependent high affinity choline uptake in vitro. This portion of choline uptake may be regulatory in the synthesis of acetylcholine [ACh]. The Na+-dependent high affinity choline uptake may be used as a measure of the relative state of cholinergic activity in vivo. A number of drugs were administered to alter turnover and release of ACh (both are measures of cholinergic activity in vivo), and subsequently Na+-dependent high affinity choline uptake in vitro was examined. Administration of pentobarbital, chloral hydrate, morphine, physostigmine, .DELTA.9-tetrahydrocannabinol [.DELTA.9-THC], hemicholinium-3 and oxotremorine, drugs which decrease ACh turnover and release, caused a reduction in choline uptake. Conversely, administration of pentylenetetrazol, atropine, scopolamine, and haloperidol, drugs which increase ACh turnover and release, caused an increase in choline uptake in vitro. Na+ dependent high affinity choline uptake can apparently be used as a relative measure of the activity of cholinergic neurons in vivo.
